Be it known that l, ARGHILLES A. BARTON, a citizen of the United States, residing in Glendale, in the county of Los Angeles and .State of California, have invented a new and useful Pump, of which' the following is a specification. v f

My invention relates to pumps, and the object of my invention isto provide a pump in which the working stresses are balanced andequalized and which will have certain advantages as to Construction, operation and maintenance as set forth more in detail hereinafter.

Referring to the drawings, which are for illustrative purposes only,

Fig. 1 is a front elevation tion.

F ig. 2 is an elevation partly in section on a bent plane represented by the line 2-2 of Fig. 1 and Fig. 3.

Fig. 3 is a plan.

In the form of my invention illustrated in the drawings, a base 11 is provided, this base resting upon and being supported by two slide rails 12 which may conveniently rest upon a concrete, masonry or timber foundation 13. The base 11 is provided with pedestals 15 at either side thereof, these pedestals having bearings 16 and 17 in which a main shaft 18 and a counter shaft 19 are journalled. The counter shaft 19 may be provided with a driving pulley 2O partly in secand with a pinion 21 meshing with a gear 22 carried on the rmain shaft 18. Footings 25 are secured by bolts to the base 11 and carry guide rods 27 which are arranged in pairs and which are connected in pairs into top castings 28, these castings all being tied together by means of an upper cross channel member 29. The castings 28 also receive struts 30 which are secured in bottom Castings 31 carried by a lower cross channel member 32 which extends across the rear of the pump between the pedestals 12.

Sliding on each pair of guides 27 is a reciprocating head 39 which may conveniently be formed of an upper casting 40 and a lower casting 41, these castings being connected together by four tie rods 42. Turning on upper and lower stub shafts 43 and 44 in the upper and lower heads respectively are upper and lower rollers 45 and 46. Rigidly secured on the shaft 18 are three cams 50, each of these cams being so placed that it acts against one set of rollers 45 and 46 to move one of the heads 39 up and down.

Secured in each of the two outer castings 41 by means of nuts 51 is a polish rod 52, and secured to the casting 41 of the center head is an inner pump rod 63, these polish rods and this pump rod passing through stuing boxes 53 in a cover 54 of a dischargeA 'l' 55. The discharge 'l' and the cover 54 are secured by means of bolts 56 to the bottom of the frame 11. The cams 50 are so arranged that the outer polish rods move together', the central cam being `set 180 degrees in advance of the outer cams so that the pump rod 63 moves in a practically reverse direction to the polish rods, the cam being so proportioned that any desired amount of overlap in the stroke may be obtained in accordance with standard pump practice. The polish rods are connected to a beam which is pivoted at 61 on an outer pump rod 62. A stuing box 64 is provided between the inne:y pump rod 63 and outer pump rod 62. A fiange connection is provided on the side of the discharge T 55 through which water is discharged and to which the discharge pipe (not shown) ma;7 be connected.

The method of operation of the invention is as follows:

Power being supplied through the pulley 20. the shaft 18 is rotated from the shaft 19 in the direction shown by the arrow in Fig. 2 through the gears 21 and 22 and the cams 50 are rotated. moving` the heads 39 up and down on the `guides 27. the two outer heads 39 being approximately the same level at all times and moving in synchronism with each other, the central head 39 being operated by the central cam which is placed at an angle to the two outer cams. The reciprocating motion is transmitted through the outer polish rods 52 to the beam 60 and through it to the outer pump rod 62, the inner pump rod- 63 being worked direct from the center head 39. The outer and inner pump rods 62 and 63 are connected to buckets (not shown) which are located near the bottom of the well in accordance with standard deep well duplex pump practice. Water is pumped upwardly through the well column 80. being delivered into the discharge T 55 and passing outwardly through the flanged connection 70.

Whenever it is desired to pull the rods the nuts 51 are loosened thus allowing the inner and outer pump rods to drop down so that the entire pump head carried by the base 11 can be slid away from the mouth of the Well on the rails 12. rIhis rendersl the cover 54 accessible and it is taken off,

thus giving full access to the interior of the Well.

The advantages of the construction above described over the previous art are in part as follows:

(a) By placing the beam 60 inside the dis charge T 5.3 I am able to produce a pump head Which is very loiv and stable thus largely eliminating vibration and reducing cost.

(Z9) B using three cams symmetrically placed aout the center plane of the head I am able to equalize strains at right angles to this plane and thus eliminate vibration.

(c) By using guide rods 27 which are located to the right of the shaft 18 and by rotating the shaft 18 in the direction of the arrow as seen inFig. 2 I am able to place the horizontal component of the cam thrust largely ony the struts il() which are in compression and therefore relatively stiff.

What I claim is 1- 1. In a pump, a Well column, a discharge T secured in Water tight relationship to said column, a cover for said discharge T, an inner pump rod passing through said Well column'and into said discharge T, an outer pump rod surrounding said inner pump rod, a beam pivoted on said outer pump rod, two polish rodsone of which is securedV to each end of said beam and each of which passes through 4'said cover, through which the inner rod also passes, means for making a tight joint between said inner and outer pump rods, and means for making a tight joint around each of said polish rods and said inner pump rod Where they pass through said cover.

2. A. pump head comprising` a base, pedestals formed on said base, bearings 'on said pedestals, a mainshaft carried in said'bearings, three cams on said main shaft, three reciprocating heads each cooperating with one of said cams, guidingmeans foil each of said heads, tivo polish rods each connected to one ofthe tvvo outer heads, an inner pump rod Connected to the center head, a discharge T into which said polish rods and said pump yrods extend, a cover for said T through v/hichsaid polish rods and said inner pump rod pass, meansfor making a tight closure about said rods Where they pass through said cover, a Water column connected into said T and through Whichy said inner pump rod passes, an outer pump rod surrounding said innerpump rod, and means insidesaid discharge T connecting said polish rods With said outer pump rod.

In testimony whereof, I have hereunto set :ly hand at Los Angeles, California, this 20th day of March, 1919.
